+Subject: [PATCH] linux-user: fix to handle variably sized SIOCGSTAMP with new
+ kernels
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+The SIOCGSTAMP symbol was previously defined in the
+asm-generic/sockios.h header file. QEMU sees that header
+indirectly via sys/socket.h
+
+In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
+the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
+Instead it provides only SIOCGSTAMP_OLD, which only uses a
+32-bit time_t on 32-bit architectures.
+
+The linux/sockios.h header then defines SIOCGSTAMP using
+either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If
+SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even
+on 32-bit architectures
+
+To cope with this we must now convert the old and new type from
+the target to the host one.

+Backport of QEMU v4.1 commit for stable v4.0.1 release

+    q35: Revert to kernel irqchip
+
+    Commit b2fc91db8447 ("q35: set split kernel irqchip as default") changed
+    the default for the pc-q35-4.0 machine type to use split irqchip, which
+    turned out to have disasterous effects on vfio-pci INTx support.  KVM
+    resampling irqfds are registered for handling these interrupts, but
+    these are non-functional in split irqchip mode.  We can't simply test
+    for split irqchip in QEMU as userspace handling of this interrupt is a
+    significant performance regression versus KVM handling (GeForce GPUs
+    assigned to Windows VMs are non-functional without forcing MSI mode or
+    re-enabling kernel irqchip).
+
+    The resolution is to revert the change in default irqchip mode in the
+    pc-q35-4.1 machine and create a pc-q35-4.0.1 machine for the 4.0-stable
+    branch.  The qemu-q35-4.0 machine type should not be used in vfio-pci
+    configurations for devices requiring legacy INTx support without
+    explicitly modifying the VM configuration to use kernel irqchip.

+kernel module loaded before running kvm. The easiest way to ensure that the
+kernel module is loaded is to load it on boot.
+	For AMD CPUs the module is called 'kvm-amd'.
+	For Intel CPUs the module is called 'kvm-intel'.
+Please review /etc/conf.d/modules for how to load these.
+
+Make sure your user is in the 'kvm' group. Just run
+	$ gpasswd -a <USER> kvm
+then have <USER> re-login.
+
+For brand new installs, the default permissions on /dev/kvm might not let
+you access it.  You can tell udev to reset ownership/perms:
+	$ udevadm trigger -c add /dev/kvm
+
+If you want to register binfmt handlers for qemu user targets:
+For openrc:
+	# rc-update add qemu-binfmt
+For systemd:
